heat-seal
Weld with warmth
Heat-seal means to join materials, usually plastic or foil, by applying heat and pressure.
The process melts surfaces together to form an airtight bond: heat-sealed packaging, The bag was heat-sealed to preserve freshness.
Common in food packaging, medical supplies, and any application requiring a tamper-evident or moisture-proof closure.
